after fully set forth.

The object of my invention is to provide a light, durable, effective, and economical apparatus, specially adapted for use in deep wells,

or in mines where different levels or stations areestablished.

Referring to the accompanying drawings, Figure 1 is a perspective view of my pumping apparatus. Fig. 2 is a plan of the top of shaft, showing the traveler L at the extent of its forward stroke. Fig. 3 is a plan of same, showing said traveler at the limit of its return-stroke. Fig. 4 is a vertical section of Fig. 3, showing band m. Fig. 5 is avertical section taken on line 3 4, Fig. 2, showing bands a. Let A represent the shaft of a deep mine having any number of side stations at suita ble levels. I have here shown three such stations, upon the upper two of which are pumps B B, set in a horizontal position, while at the lowest station is the pump B set vertically, the object ofwhich I shall hereinafter explain. At the surface of thegronnd, and across the month of the shaft A, is mounted a shalt, 0, upon which is secured a pulley, D.

Extending from each of the various stations or levels are short shafts 0, each carrying double-faced pulleys D D D all of which are here in a vertical plane with the pulley D, at one side of the shaft A. Ulamped upon top of the face of pulley D is a flat cable or belt, E, the ends of which pass over the sides of the pulley and hang down in the shaft. The cableE maybe a fiat wire cable, or a chain, as maybe necessary. Glamped to the tops of the next two pulleys, D D upon their outer faces, are similar flat cables or belts, E E respectively, the ends of which hang down on each side.

Under the three pulleys D D D upon their I inner faces, are clamped flat cables F F F,

.2 and 5.)

the pulleys, and are connected with the depending ends of the flat cables E E E respectively, by round cables, chains, cords, or ropes G, thus completing the connection between all the pulleys D D D D, so that the oscillation of the driving-pulley D will oscil late the other three.

The intervening round cables G are provided with tightening-nuts or turn-buckles g, whereby the slack of each may be taken up. i

To produce the oscillating movement of the the ends of which extend up over the sides of driving-pulley D, l have the following apparatus H represents a suitable foundation, on which is here shown a steam-cylinder, I, having within a suitable piston, the rod J of which is shown as extending from the cylinder-head.

In the frame H are mounted two parallel horizontal rods or tracks, K, upouwhich'a traveler, L, is adapted to reciprocate. end of the piston-rod J is connected with this traveler, to which it transmits a reciprocating rectilinear motion.

Secured upon the shalt O is a-pulley, M, having three faces. (See Figs. 4 and 5.) A band or belt, m, is clamped upon the top of the central face, and thence passes loosely around one side of it and under the pulley, and is secured to the end of the traveler nearest the steam-cylinder, Figs. 3 and 4. Two similar bands or belts, n, are clamped to the outer faces, thence pass loosely around and under the pulley in an opposite direction to that of the central band and are secured to the opposite end of the traveler. (See Figs. These bands or belts in it may be constructed of any material, and may be flat The wire cables or chains, according to circum- ICC Secured upon the shafts C are pulleys M, having three faces. Bands or belts m n are clamped upon these faces and pass loosely around them, being secured to opposite ends of the travelers L, the arrangement being similar to those of pulley M and traveler L above. The bands m a may likewise be flat wire cables or chains. Thus the oscillating movement of pulleys D D D is transmitted to the pump-rods in arectilinoar reciprocating motion to operate the pumps.

These pumps are supposed to be doubleacting pumps, and are connected with each other through. suitable pipes and intervening tanks, or in any appropriate manner.

It will be observed that 1 have arranged the pump B in a vertical position. I do this in order to make it the lift-pump. A pump-rod, N, extends downward from the lower end of the traveler. This rod may be supposed to reciprocate a suitable plunger in a pump-cylinder lower down, whereby the water is raised to the pump B The principle of action is the same whether the pump be placed in a vertical or in a horizontal position. This conversion of rectilinear to oscillating motion, and vice versa-,while being simple, is advantageous in overcoming the dead-center of crank-motion for one-half of a circle.

Although I have here shown the pumping apparatus in a shaft of a mine, it is obvious that the same apparatus is applicable to adeep well. In all ordinary cases of this character no stations would be required other than the one near the bottom, where the pump would be supported. This could be in any practicable manner, either entirely submerged, in which case there would be no danger from leakage orabove the level of the water. The suction-pipe, could extend down to the water, and the dischargepipe extend from the valvechamber to the curb or mouth of the well. The pump-rod would be reciprocated in the manner already described by the oscillating pulley, connected through belts and chains with an oscillating driving-pulley receiving motion from an engine or a hand-crank, as might be desirable. The connecting round cables should preferably be made of wire laid up parallel, not twisted.

The operation of the pump B as a lift-pump has a tendency to throw'the system out of balance by the amount of force required to operate it. This may be overcome by adjusting the cut-off of the steam-engine, allowing'it to admit more steam at one end than at the other. When the required depth of shaft is reached the lift-pump may be. dispensed with.

This apparatus will work at any angle desired by fastening the chains or cables at the v center of the pulleys on a line in the new direcclaim as new, and desire to secure by Letters Patent, is

1. The traveler L and means for reciprocatingit, in combination with the pulley M, and. the belts or bands m a, secured to the pulley on top, and attached at opposite ends to the reciprocating traveler L, substantially as herein described.

2. The steam-cylinder I and piston-rod J, and the reciprocating traveler L, to which said rod is attached, in combination with, the polley M, and the belts or bands m a, secured to the pulley on top, and attached at opposite ends to the reciprocating traveler L, substantially as herein describe 3. In a pumping apparatus the traveler L- for connecting the two to transmit the oscillation of the pulley D to pulley D, in combination with the pulley M, on the shaft with pulley D, the pump B, pump-rod J, and means for reciprocatingsaid rod, consisting of the reciprocating traveler L and bands m n, attached to the pulley M on top and secured to opposite ends of the traveler, substantially as herein described.

5. In a pumping apparatus, the power-pub ley D and means for oscillating it, consisting of the reciprocating piston-rod J and traveler L, pulley M, and bands at 02, arranged as shown, in combination with the pulley D be low, a connecting band or belt between it and pulley D, pulley M, bands m a, traveler L, pumpB, and pump rod J, a'll arranged and operating substantially as herein described.

A pumping apparatus for deep wells and mines, consisting of the power-pulley D, means for oscillating it, consisting of the reciprocating piston-rod J, traveler L, pulley M, and bands m n, the double-faced pulleys D D D at each of the levels or stations, the flat cables E E E attached to the tops of pulleys l) D D and extending down, the flat cables F F F attached to the bottoms of pulleys D D D and extending up, the intervening round cables G, securing the flat cables together, the pumps B B B rods J, reciprocating travelers L, oscillating pulleys M on same shafts with pulleys D D D and the bands m n, all arranged and operating substantially as herein described.

In witness whereof I hereunto set my hand.
